World Of Chemistry 2nd Edition - Solutions by Chapter

The amount of product actually obtained in a reaction. (3.10)

The position immediately adjacent to a functional group.

A solution in which water is the solvent. (Chapter 4: Introduction)

Hydrocarbon compounds that contain a planar, cyclic arrangement of carbon atoms linked by both s and delocalized p bonds. (Section 24.2)

The distance between the nuclei of two bonded atoms in a molecule. (9.4)

A structure that bears a positive charge.

An effect that causes different regions of space to be characterized by different magnetic field strengths.

The enthalpy change associated with a chemical reaction. (Section 5.4)

A thermodynamic function associated with the number of different equivalent energy states or spatial arrangements in which a system may be found. It is a thermodynamic state function, which means that once we specify the conditions for a system—that is, the temperature, pressure, and so on—the entropy is defined. (Section 19.2)

The quantity of heat required to raise the temperature of a sample of matter by 1 °C (or 1 K). (Section 5.5)

A term that describes the position of equilibrium for a reaction: Keq = 3H3O+ 4 3A- 4 3HA4 3H2O4

A CH2 group.

The very small, very dense, positively charged portion of an atom; it is composed of protons and neutrons. (Section 2.2)

Polymers made up of repeating urethane groups, also sometimes called carbamate groups (!N!CO2!).

A measure of the force exerted on a unit area. In chemistry, pressure is often expressed in units of atmospheres (atm) or torr: 760 torr = 1 atm; in SI units pressure is expressed in pascals (Pa). (Section 10.2)

A constant of proportionality between the reaction rate and the concentrations of reactants that appear in the rate law. (Section 14.3)

A measure of the decrease in concentration of a reactant or the increase in concentration of a product with time. (Section 14.2)

An organohalide in which the alpha (a) position is connected to exactly two alkyl groups.

A compound containing three hydroxyl groups.

A carbocation in which the positive charge resides on a vinylic carbon atom. This type of carbocation is very unstable and will not readily form in most cases.
